Amphenol ICC 68685-205LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68685-205LF is a 5-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 905 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or supply constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68685-205LF are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 5 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening type
• Electrical Performance: Gold-plated mating contacts with solder-compatible post finish
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance

The identified substitutes (TE Connectivity 215297-5 and Samtec ESS-105-T-03) meet these core requirements. Variations in insulation material, contact finish thickness, and insulation height represent acceptable engineering tolerances within the rectangular connector category and do not preclude functional substitution in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 215297-5: This substitute maintains identical mating pitch, position count, and fastening mechanism. Both parts carry RoHS compliance and UL94 V-0 flammability certification. The kinked pin termination option in the TE part provides enhanced mechanical retention during solder reflow. Insulation height and contact post length are equivalent. This part is suitable for direct substitution in applications where the original 68685-205LF is unavailable.

Samtec ESS-105-T-03: This elevated socket connector maintains the critical 0.100" pitch and 5-position configuration with identical fastening and termination methods. The elevated socket design provides increased clearance for mating plug connectors. The part carries ROHS3 compliance (exceeding RoHS requirements) and UL94 V-0 certification. The slightly increased insulation height (0.300" vs. 0.276") and contact post length represent minor dimensional variations acceptable in standard board-to-board interconnect applications. This part is suitable for substitution where elevated socket geometry is compatible with the application PCB layout.

Both substitutes are active production parts with established inventory availability and meet the core electrical and mechanical requirements of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 215297-5 be used as a direct replacement for the Amphenol ICC 68685-205LF?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (5), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). Both carry UL94 V-0 and RoHS compliance. The kinked pin option in the TE part provides additional mechanical retention and does not prevent substitution.

Q: What is the difference between the standard receptacle (68685-205LF) and the elevated socket (ESS-105-T-03)?

A: The elevated socket design in the Samtec part provides increased vertical clearance between the PCB and the mating connector interface. This is beneficial in applications where space above the PCB is limited or where multiple connector layers require clearance. The mating pitch, position count, and electrical performance remain equivalent.

Q: Are there dimensional compatibility concerns when substituting the Samtec ESS-105-T-03?

A: The Samtec part has a slightly increased insulation height (0.300" vs. 0.276") and contact post length (0.123" vs. 0.115"). These variations are within standard tolerances for rectangular connectors in this category. PCB layout compatibility should be confirmed for applications with tight vertical spacing constraints.

Q: Do all three parts meet the same compliance standards?

A: All three parts carry UL94 V-0 flammability certification and RoHS compliance. The Samtec part carries ROHS3 compliance, which exceeds the RoHS requirement. All parts are classified as EAR99 for export control purposes.

Q: What is the difference in contact material between these parts?

A: The Amphenol ICC 68685-205LF uses phosphor bronze contacts, while the Samtec ESS-105-T-03 uses beryllium copper contacts. Both materials are standard for rectangular connectors and provide equivalent electrical performance in this application category. The TE Connectivity 215297-5 also uses phosphor bronze contacts.

Q: Can these parts be used interchangeably in automotive and industrial applications?

A: Yes. All three parts are rated for automotive, general purpose, industrial, and telecommunications applications. The push-pull fastening mechanism and gold-plated mating contacts provide reliable performance across these application categories.
